AECOPD research in the past ten years: a bibliographic analysis based on Web of Science

Abstract

Background: Acute exacerbations of chronic obstructive pulmonary disease COPD (AECOPD) caa significant decrease in patient lung function, and are the main reason for hospitalization and dpatients with COPD. This study aims to use bibliometric methods to analyze the characteristics of AErelated research in the past 10 years [2010–2020] and provide references for future research. Methods: This study used subject terms to search AECOPD-related documents published in 201in the Science Citation Index Expanded (SCI-E) database. The search terms were “AECOPD” or exacerbation of chronic obstructive pulmonary disease.” We use the CiteSpace software to analyze the literature records. The analysis includes: the annual distribution of literature publications, the distribupublished literature sources (including countries, institutions, journals, and authors), and using keyworResults: A total of 3,785 articles on AECOPD were published between 2010 and 2020, with citations. Both the number of published documents and the number of citations has increased witThe literature mainly comes from several developed countries, including European and North Amcountries, and the cooperation between institutions and authors in these countries is relatively The main journals are the top journals of respiratory specialty and the top comprehensive journaresults of the keyword analysis show that the current research is on risk factors, biomarkers, and AEmanagement. Conclusions: AECOPD research tends to focus on a precise diagnosis and treatment, and prevenAECOPD in patients with COPD should be paid more attention.
